Sample Flashcard Questions & Answers

Showing 8 of 50 cards
Question #1 Active Recall

What is the slope-intercept form of a linear equation, and what do m and b represent?

Answer & Explanation:
y = mx + b, where m is the slope (rate of change, rise/run) and b is the y-intercept (the value of y when x = 0).
Question #2 Active Recall

How do you calculate the slope (m) of a line passing through two distinct points (x1, y1) and (x2, y2)?

Answer & Explanation:
m = (y2 - y1) / (x2 - x1)
Question #3 Active Recall

Under what condition does a system of two linear equations in two variables have NO solution?

Answer & Explanation:
When the lines are parallel (they have identical slopes: m1 = m2) but distinct y-intercepts (b1 != b2).
Question #4 Active Recall

Under what condition does a system of two linear equations have INFINITELY MANY solutions?

Answer & Explanation:
When the two equations represent the exact same line (identical slopes: m1 = m2 AND identical y-intercepts: b1 = b2).
Question #5 Active Recall

If a line has an equation in standard form Ax + By = C, what are its slope and y-intercept in terms of A, B, and C?

Answer & Explanation:
Slope m = -A/B and y-intercept = C/B (provided B != 0).
Question #6 Active Recall

What is the relationship between the slopes of two perpendicular lines in the Cartesian coordinate plane?

Answer & Explanation:
Their slopes are negative reciprocals: m1 * m2 = -1 (or m2 = -1/m1), provided neither line is vertical or horizontal.
Question #7 Active Recall

How do you solve a linear inequality such as -3x + 7 >= 22?

Answer & Explanation:
Subtract 7 from both sides (-3x >= 15), then divide by -3 and FLIP the inequality sign: x
Question #8 Active Recall

What does the x-intercept of a linear function f(x) represent geometrically and algebraically?

Answer & Explanation:
Geometrically, it is the point where the line crosses the x-axis; algebraically, it is the value of x when f(x) = y = 0.
